ANSI/UL 94材料可燃性測試– 標準名稱
ANSI/UL 94Test for Flammability of Plastic Materials for Parts in Devices and Appliances
ANSI/UL 94設備及電器塑料部件的標準燃燒測試方法。
ANSI/UL 94材料可燃性測試 – 標準概述
這些要求涵蓋了用于設備和器具部件的聚合物材料的可燃性測試。它們旨在作為其對特定應用的可燃性的可接受性的初步指示。
These requirements cover tests for flammability of polymeric materials used for parts in devices and appliancesThey are intended to serve as a preliminary indication of their acceptability with respect to flammability for a particular application.
ANSI/UL 94 VTM薄質(zhì)材料的垂直燃燒測試 –測試標準
當采用20mm垂直燃燒測試時，由于測試材料薄、扭曲、收縮或燒致夾具而無法進行，本測試方法就是針對這種材料規(guī)定的測試方法。該類材料還具有使長度為200mm，寬度為50mm的試樣，縱向纏繞在13mm直徑的卷軸上的物理性能。
This test is intended to be performed on materialsthat due to their thinnesseither distortshrinkand/or are consumed up to the holding clamp when tested using the test described in the 20 mm Vertical Burning Test.This test shall only be performed after it has been determined that the samples cannot meet the requirements of the 20-mmVertical Burning Test The materials shall also possess longitudinally around a 13 mm diameter mandrel
